shell32: Check CPL_NEWINQUIRE message in control panel applets if we can't retrieve valid strings/icon

This patch helps to fix an issue discovered while debugging bug #5891.
The cpl linked to in that bug demonstrates an issue whereby a malformed
control panel applet can return seemingly valid data in the CPL_INQUIRE
request, but this data then turns out to be invalid (the strings and
icons it refers to do not exist in the cpl's resources). The
CPL_NEWINQUIRE message, in this case, does send the correct details.
This patch modifies the control panel so that it also tries
CPL_NEWINQUIRE if it gets a zero-length applet title, or a null icon.
(CPL_NEWINQUIRE was introduced in Windows 3.1 and was considered the
preferred mechanism then, however, Windows 95 and later favour the
original CPL_INQUIRE, which is what most applets implement.)
A separate patch will follow to fix the same issue in the shell-based
control panel.
